SPECIFICATION forming part of `Letters Patent No. 760,587, dated May'24, 1904.

Application filed mmh s, 1.904.

To @ZZ whom t may concern: Y'

Be it known that I, JUsTUs A. TRAUT, a

citizen' of the United States, residing at New Britain, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements'in Levels, of which the following is a full, clear, and exactdescription. My invention relates to improvements in levels.

,The object of my invention is to provide a structure of simple and reliable character which may be readily adjusted'when desired.

The invention consists in mounting a levelglass in a beam of suitable character in such a manner that it maybe adjusted when desired by a simple movement, theparts being then clamped securely in place.` The details y will be more clearly seen on an inspection of the accompanying sheet ofy drawings.

2O Figure l is a perspective' view of a level embodying the impro v ements of my invention. Fig. 2 is a section and plan view of the same. Fig. 3 is a fragmentary front view of a levelbeam, the level being sectioned immediately back of the front plate. Fig. 4 is a vertical section of those parts of the construction which embody the improvements of my invention.

1 indicates a beam'or block to which the level of my construction vis adapted to be at- 2 is the level-.glass of suitableconstruction containing a suitable fluid.` I

3 is a frame or support for the level-glass 2. This frame or supportis preferably in the form of a cylinder yand is provided with holes on opposite sides to receive'the ends of the level-glass, the latter being secured in said holes in any "well-known manner, so'that as the frame is moved or adjusted the level-glass 40 will move to a corresponding extent and be adjusted to correspond with'the adjustment of said frame. 4

4 is adisk formed as the flangeof the cy1- inder 3.

5 and 6 are screws for holding the parts in Serial No. 197,146. (No model.)

through it to permit of the insertion of the 3. For the samel reason the recesses which allow for the ends of the level-glass are eX- tended, as shown.

7 is an annular disk or plate which corresponds to the flange 4 and is let into the rear side of the'level-beam. The screws 5 and 6 take into thisiange 7, and thus clamp the parts securely together.

To enable "one to adjust the level readily, I

have formed a recess,as at 8,in the outer flange 4. When the screws 5 and 6 are loosened, a screw-driver or other tool may be applied to a recess in the iiange for slightly twisting the level in one direction or Vthe other. Similar recesses, as at 9, are p referably provided in the rear iiange 7, so that the `parts may be adjusted without binding. yThe advantages of this construction are particularly its simplicity and general efficiency, which, moreover, permits of a quick and reliable method of adjustment.

What I claim is-.

A level comprising a beam having an opening therethrough, a frame located in said opening, a level-glass supported thereby, a ange coacting with said frame at each end thereof and substantially liiush with the outer surface of said beam, said beam having elongated openings, and screws passing through .said elongated openings and connectingl said anges for clamping the same adjustably in position.
